: you are right; the lower horse shoe connector is difficult to reach. Space is tight with a lot of interference to touch the connector
Decide to just order the part and have mechanics shop to install
I just tried to pull off the broken hose but only be successful to take off the top connector, not even with the press-in fitting
Could they make it any tighter in there??!!!! LoL! 😂
Yes, for $20, replace with the original part.
Note, if the dealer can't get you in for a couple weeks...
From the photo it looks like that hose has several inches of slack in it. if so, what you could do in the interim is to cut the rubber hose (which you'll be replacing anyway) right at where the part of the plastic from the connector is broken off in there exposing clean hose. See #1 below.
Then using the slack in the hose, pull it up and connect it to the stub on #2. There looks like there's enough stub left to get a clamp around and you can see from the cross-section of that connector, it's nice and thick so shouldn't collapse if you tighten it well with a worm-gear hose clamp.
It's not ideal of course but heater hoses don't have a lot of pressure going through them. If you do this, also rough-up the surface of that stub end with some sandpaper so the clamp/hose can grip better.
Just a thought if an emerg.
